Iwatani Yori is a 39-year-old woman who leads a quiet life while working at the library. She considers things like love and marriage to be too troublesome. A handsome, yet suspicious man approaches her, claiming to be an old childhood friend. Maki has cared for Yori since he was a boy, but now he is a married man - married to a woman who looks exactly like Yori. This apparently does not stop him from pursuing Yori, who desperately tries to push him away. What kind of future could this love (?) have?
